For the diver’s bezel of this interesting timepiece, we are using a bronze alloy we developed, which is patented. This alloy, referred to as Goldbronze 125, has an exceptionally high degree of purity, and one eighth of it is gold. With bronze, we are embracing a material that has been used frequently in a wide range of maritime applications in the past. However, the exceptionally high degree of purity of our Goldbronze 125 results in improved skin compatibility and increased corrosion resistance to seawater compared to conventional bronze alloys. Material-technically matching this, the case of the T50 GBDR is made of high-strength titanium. As this metal does not cause allergies, the watch provides exceptionally high wearing comfort overall. Goldbronze 125 continues to develop a darkening of the surface due to oxidation, also known as a patina. However, the alloy achieves a higher degree of inertness in the face of environmental influences than ordinary bronze (CuSn8) because it has gold as a component. If desired, the mentioned darkening of the surface can be removed with a gold bronze cleaning cloth provided that the oxidation is minimal enough.
